Lt. Gen. Mark A. Ediger (left), Surgeon General of the Air Force, passes the Air Force Medical Operations Agency guidon to Brig. Gen. Robert I. Miller (center), incoming AFMOA commander, during a May 6 change of command ceremony at Port San Antonio. In military tradition, the passing of a unit guidon signifies relinquishing or accepting command of that unit. (U.S. Air Force photo / Tech. Sgt. Christopher Carwile.)
